Title: Serial communication equipment
Inventor: HASHIMOTO HIROBUMI
IPC: H04L1/00
Filed: 1988-08-30
Abstract: PURPOSE:To improve the transmission efficiency by using a received error signal or busy signal sent from a receiver side so as to revise the transmission rate. CONSTITUTION:When a data RXD received this time is reception error information sent by an opposite station (reception of a reception error signal), a communication LSI2A outputs an error detection signal 6, and when a baud rate generator 3 upon the receipt of an error detection signal 6 outputs a transmission clock whose frequency (transmission rate) is decreased by a prescribed quantity. Thus, a serial communication equipment upon the receipt of a reception error signal RXD decrease the transmission rate automatically at the next transmission to send a data TXD and a transmission clock TXC and decreases further the transmission rate when the reception error signal RXD is received successively. When no reception error signal RXD is inputted, that is, normal communication is finished, the serial communication equipment increases the transmission rate by a prescribed value each conversely at each transmission time till the transmission rate reaches a prescribed upper limit. Thus, the transmission efficiency is improved.

Abstract: PURPOSE:To provide a magnification varying function and to obtain small-sized constitution by fixing an original surface,image surface, and lens position, forming optical paths before and behind a lens as a going and a returning optical path, and varying them in length. CONSTITUTION:An original exposure position 4, an exposure position 14 on a photosensitive drum 15, and the position of the lens L are fixed, and optical paths before and behind the lens L are formed through mirrors 6 and 7, and 11 and 13 as a going and a returning optical path; and the mirrors at mirror positions 6, 7, 11, and 13 for life size are moved to mirror positions 6', 8', 11', and 13' for 0.5 magnification or to mirror positions 6'', 8'', 11'', and 13'' for 1.4 magnification, thus varying the optical paths in length. Thus, the mirror system is only moved mechanically to perform contraction and enlargement over a wide range, and the length of the front and rear optical paths is equal to that of the going and returning optical paths, so the extent of mechanical movement required for variation in optical path length is reduced to half, thereby reducing the size of the device.

Title: Pickup driver for disk player
Inventor: KAMIMURA TETSURO
IPC: G11B21/02
Filed: 1993-08-30
Abstract: PURPOSE:To prevent floating of a rack from a feed screw member, fluctuations of engagement, a positional deviation of a pickup by bringing the member into pressure contact with the rack having a rotary fulcrum. CONSTITUTION:When a pickup member is fed, a contact resistance is generated at an engaging surface of a rack 49 with the feed screw 46. A component force which tends to flat the rack 49 from the screw 46 is operated by the contact resistance. Since the rack 49 is brought into pressure contact with screw 46 against the component force, the rack 49 can accurately feed the member without gap between a tooth surface and the crests of the screw 46. Further, the rack 49 is brought into pressure contact with the screw 46 in a state that the tooth surface is inclined obliquely upward to a horizontal line for connecting left and right guide rails 35. Thus, fluctuations due to vibrations in horizontal and vertical planes can be prevented by the pressure contact.

Title: Stage control method, stage device and aligner
Inventor: HASHIMOTO TAKEYUKI
IPC: G03F7/22
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To reduce the time for determining total position for both stages for rough movements and fine movements, and to determine the position of the stage for fine movements with stability, in a method for controlling stages, stage devices and an aligner. SOLUTION: A step for driving and controlling a stage 11 for fine movement up to a target position is performed by switching between a step for controlling, on the basis of the distance of transfer from the start position to the actual position of a stage 10 for rough movements according to the transfer distance from the start position to the target position of the stage 10 for rough movements and a step for controlling on the basis of the transfer time from the start time of the stage for fine movements and the actual time. In this way, when the transfer distance of the stage for rough movements is small, the position of the stage for small movements is determined through control based on the transfer time separately from the stage for rough movements, even if they start to move at the same time. Accordingly, a stable positioning can be performed with an acceleration under a limit, without dependence on a large acceleration.

Title: Liquefied gas subcooler and pressure regulator
Inventor: ERITSUKU ERU JIENSEN
IPC: F17C13/02
Filed: 1988-08-29
Abstract: PURPOSE: To obtain a subcooler for supplying a liquefied inert gas to industrial processes by arranging a chamber with a flow control valve communicating with a liquefied gas source, a column packed with a liquefied gas provided below the chamber and a gas outflow tube surrounding the column. CONSTITUTION: When an inflow pipe 12 is connected to a liquefied gas source and a valve 10 is opened, a liquefied gas enters a chamber 15 and passes through an opening 20 and a column 22 to cool the interior thereof. Then, it is rapidly gasified to be released from a path 30. The liquid and the gas continue to flow in until the chamber 15 and the column 22 reaches a balance in temperature. When the balance in temperature is reached, a float 18 rises with a rise in the water level in the chamber 15 to close an inlet by a valve stem 16. When the vaporized foams ascend in an outer tube 28, the liquid in the column 22 is forcibly circulated to lower the liquid in the column 22. At this point, an evaporation occurs to lower the temperature of the liquid. With such an arrangement, a sub cooler is obtained to supply a liquefied inert gas to industrial processes.

Abstract: PURPOSE:To maintain proper operating temp. and operate a fuel battery with high efficiency by furnishing a coolant heater using a fuel battery as power supply, wherein the battery is installed in the cooling system, and a control part for operating the heater in the low-load operating range of battery. CONSTITUTION:In the high-load operating range of the battery body 1, the degree of opening of a damper 8 is adjusted on the basis of output from a temp. sensor 15 so as to maintain proper operating temp. When a drop of battery load sinks the temp. of the body 1 and the sensor 15 senses that the temp. is below the set level, a damper 6 is shut upon command from a control part 14, to shut off the external air supply to the cooling system 5. Now fuel battery operates a coolant heater 13, and the heater output is controlled on the basis of difference from the set temp. value and the rate of temp. change. By heater heating, on the other hand, temp. rise of the cooling air and the amount of heat emission by the battery itself apply in synergetic effect, and the body 1 is prevented from excessive temp. drop even in the low-load operating range of the battery to ensure maintenance of proper temp., which allows the battery to be operated with high output characteristic. When a specified temp. is exceeded, the heater 13 is stopped and damper is opened, and transfer is made to operating temp. adjustment in the cooling system 5.
